,GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 250,793, dated December13, 1881.

Application led September 5, 188].

To all whom it may concern Be it known that I, FERDINAND DIEGK- MANN, ofCincinnati, in the county of Hamilton and State of Ohio,have inventednew and useful Improvements in Gas-Burners, which improvements are fullyset forth in the following specification, reference being had to theaccompanying drawings.

The object of myinvention is to produce a gasburner made from thinsheet-metal plates, and so constructed th atby the application of asinall amount of heat it will generate gas from the very heaviest as wellas the lightest hydrocarbon oils. To do thisI use certain forms andmodes ofconstruction, which must be described in detail to be thoroughlyunderstood. This burner is of that class which usually receives its heatfrom the tlame of another burner, but may be made to I'urnish its ownheat, it' desired.

Figure l shows a perspective of my burner with the needle-pointsunderneath the plates, and Fig. 2 the same with the points on top. Fig.3 shows a top View ot' the plate marked A and usually used as the lowerplate. Fig. 4 shows a sectional View of my burner, and Fig. 5 anenlarged view of the needle-poiutD with a needle in it.

Arepresents the lower plate with the edges slightly raised. This is doneto give a very small oil or gas space, T, between it and .the top plate,B. Into plate A are screwed one or more short pipes, C. These pipes arefirst screwed through the nut G, and then through the plate A until thenut rests firmly against the plate, and then both the nut and pipe areVthoroughly brazed to the plate. The pipes are made to pass through theplate about the thirtysecond part of an inch, and the end is notched, asshown at E, Fig. 3. This is to allow the oil or gas to pass from thepipe F, Fig. 1,into the pipe C, and from this into the needle-points D.These points are made in the shape ot' a T. One way they are drilled andtapped to receive the plugs H or needles J,Fig.5,as may be desired.Preferablythe needles are left out and the plugs used, that a greaterforce may be obtained for the flow of theA gas from the point; buteither may be used at pleasure.

The arm of the point marked O, Fig. 5, is drilled for the passage of oilor gas and the outside threaded to t into the short pipe C, which istapped to receive it.

(No model.)

A short pipe, L, is fitted into the plate A precisely in the same way asthe pipe C; but instead of being tapped on the inside the lower end isthreaded to screw into the oil-supply pipe F. The plate B is laid onplate'A, the edges turned over and beat down close, and then carefullybrazed all round to the plate A. This is a part ot the processthatrequires great care and skill, as upon the carefulbrazing ot' the partsdepends in a large measure the construction of the burnersuccessfully,as in this way only can such thin metal be made tight an ddurable.

This burner may be used with the pointsD and pipes G above the burner;but the oil-supply pipe AF is always placed below.

The operation of my burner is as follows: The oil from the fount beinglet into the pipe F it ows into the burner, where it is held in a verythin strata, the burner being previously heated by a taper placed underit for the purpose. The oil-globules are here mechanically divided andforced to come in contact with the highly-heated metal plates of theburner,which, having a large heating-surface, causes them to beinstantly decomposed and converted into gas. Not even the smallestoil-globule is ever allowed to pass the point D,as the outlet is eX-ceedingly small, and being filled with the eX- panded gas from theburner effectually holds the oil back' in the pipe F, while the oil inthe pipe is pressed by the oil in the fount. This counter action in theburner holds the gas till it is thoroughly decomposed and a iinegasproduced from the heaviest oils.

Vhat I claim as my invention is- 1. The plates A and B .placed inrelation to each other, as described, so that a space not exceeding onethirty-second part of an inch shall remain between them, the plate Aresting on the notched ends E of the pipes C and L, as and for thepurpose specified.

2. The burner described, consisting of the plates A and B, recess T,pipes C and L, nuts G, needle-points D, and supply-pipe F, substantiallyas and for the purpose set forth.
